Tako-Tsubo syndrome: an important differential diagnosis in patients with acute chest pain.

Background: The syndrome of Tako-Tsubo cardiomyopathy (TTC) is characterized by the occurrence of acute chest pain, electrocardiographic signs of ischemia, and transient balloon-like abnormalities in cardiac wall motion mostly involving the left ventricular apex. Significant obstructive coronary artery disease is absent. Owing to its clinical and imaging characteristics, TTC is frequently misdiagnosed as an acute coronary syndrome.
